TSK · Deuteronomy 2:16

[And] when they were gone out of the city, [and] not [yet] far off, Joseph said unto his steward, Up, follow after the men; and when thou dost overtake them, say unto them, Wherefore have ye rewarded evil for good?

And this [is] the cause why Joshua did circumcise: All the people that came out of Egypt, [that were] males, [even] all the men of war, died in the wilderness by the way, after they came out of Egypt.
